Various algorithms had an optimized implementation (for SSE2, AVX2, etc)
which was offered alongside the 'base' implementation. This is
admittedly very useful for testing, but it breaks user expectations in
bad ways. See GH #477 for background.
Now encrypting with `AES_128` (say) just runs whatever implementation
is best on the current processor/build.

If a non trival type was used, memory corruption could occur.
Original issue reported by Matthias Gierlings.

Provides conjectured 200-bit security against a quantum attacker.
Based on the public domain reference implementation at
https://github.com/tpoeppelmann/newhope and bit-for-bit
compatible with that version.

But not any ChaCha20 tests due to no long test inputs. Add one.

With the removal of Rabin-Williams, RSA is the only remaining subclass,
And it's very unlikely any new integer factorization based scheme would be
added in the future.

Testing showed no actual speedup on either i7 (SSE2) or POWER7 (Altivec),
so it is just dead weight.

XTEA was also deprecated but has been spared, it does seem to be somewhat
common (eg, included in the Go x/crypto library)

For example it used to return 0 on Linux/ARM...
If no QPC or asm version, use clock_gettime if available, or else
std::chrono::high_resolution_clock as a fallback.

Adds copyright notices for Juraj Somorovsky and Christian Mainka of Hackmanit
for the changes in 7c7fcecbe6a and 6d327f879c
Add Policy::check_peer_key_acceptable which lets the app set an arbitrary
callback for examining keys - both the end entity signature keys from
certificates and the peer PFS public keys. Default impl checks that the
algorithm size matches the min keylength. This centralizes this logic
and lets the application do interesting things.
Adds a policy for ECDSA group size checks.
Increases default policy minimums to 2048 RSA and 256 ECC.
(Maybe I'm an optimist after all.)

* --policy works for TLS Server and TLS Client
* Example policy BSI_TR-02102-2.txt
* Fine granular configuration for TLS 1.0, 1.1, 1.2 and DTLS 1.0 and 1.2
* Minimum ecdh and rsa group size

Just to avoid the unused parameter warning (we want the parameter
to be named in the header for documentation purposes, but in that
case GCC warns that the param is unused).

Make TLS::Channel::m_callbacks a reference, so deriving from TLS::Callbacks works
Split out the compat (std::function) based interface to Compat_Callbacks.
This avoids the overhead of empty std::functions when using the virtual
interface, and ensures the virtual interface works since there is no
callback path that does not involve a vtable lookup.
Rename the TLS::Callback functions. Since the idea is that often an owning
class will pass *this as the callbacks argument, it is good to namespace
the virtual functions so as not to conflict with other names chosen by
the class. Specifically, prefixes all cb functions with tls_
Revert changes to use the old style alert callback (with no longer used data/len
params) so no API changes are required for old code. The new Callbacks interface
continues to just receive the alert code itself.
Switch to virtual function interface in CLI tls_client for testing.
Inline tls_server_handshake_state.h - only used in tls_server.cpp
Fix tests - test looked like it was creating a new client object but it
was not actually being used. And when enabled, it failed because the queues
were not being emptied in between. So, fix that.
